ahahah, heres a quick fact for your nogin, before marijuana was criminalized it was the united states's #1 cash crop, yup they were farming it like fricken wheat. xD (i seen old pictures of cornfields of hemp/weed), and you know those people that go to the pen well a good portion of them join gangs in prision to protect themselves from other gangs, so not only are they putting innocent people in jail, their training (yes i say training, because thats what jail ends up being) the next wave of dangerous criminals.
Now think about this, as soon as alcohol was outlawed crime rates began to soar, there were bootleggers and smuggelers, well the states noticed these events, thats why they allowed alcohol consumption again (ALMOST INSTANTLY), now think of that on marijuana for almost the past century well what your looking at is Billions (possibly trillions) of dollars that were artificially inflated (20 fucking bucks a gram!) in the hands of gangs & drug cartels who are professionally doing this ( like i said there making billions). Well if the government wised up and just legalized and taxed the marijuana they would rake in a couple Billion, we would see a dramatic change also the marijuana prices would drop, we would pay like 60$/an oz, for cheap shit, 120$/an oz for the best. (this is my favorite part) Not to mention the medicinal quality of marijuana people wouldnt have to go through the maze of red tape just to get help for there pain! (it helps in cancer pain, as well as MS pain) we dont ask a million fucking questions at the drugstore just to get some damn advil why should they have to just to treat their chronic pain.
